SLICING-MACHINE.

Application iii-ed November '10, 1919.

To @ZZ iciom t 'may concern Be it known that I, Sonoiirox VILE, acitizen of the United States, and resident .of Rochester, in the countivof Monroe and State of \lew York, have invented certain new and usefulimprovements in Slicing- Machines, of which the following is aspecification.

The present invention relates to slicing machines and more particularlyto the type in which a rotary knife is employed in connection with atable movinpf` transversely of the turning axis of the knife, an object0f this invention being to provide an improved means through which maybe effected a relative movement between the table and the knife in thedirection of the axis of turning. Another object of the invention is toprovide a novel feeding mechanism for feeding the knife in the directionof its axis. fi. further object of the invention is to provide anautomatic means which will effect a. relative movement between the knifeand the work support in the direction of the axis of the knife.

To these and other ends, the invention consists of certain parts andcombinations of parts, allL of which will be hereinafter described, thenovel features being pointed out in the appended claims.

Fig. 13 is a detail view of thc means for holding the material upon thesupport. Referring more particularly to the drawings, i indicates theframe of the machine which may be secured to any suitable supportingmember suoli as a board 2. This frame embodies in this instance, twoside members and carries a support 3 for the 1na terial to be sliced,and a rotary cutter d which preferably is in the form of a cutting diskwith a peripheral cutting edge. The cutter and the work support are soformed that the work support may move transversely of the turning axisof the cutter while provision is made whereby a relative movementbetween the cutter and the support in the direction of thc axis of thecutter may take place. In this embodiment. this relative movement iseffected by moving the cutter in the direction of its axis` but it willbe apparent from some points of view. that the invention is not limitedto producing this relative movement by a movement of the cutter.

In order that the support for the material may partake of its movementtransversely of the axis of the cutter, this support may have two guides5 preferably on its under side and secured at opposite ends in blocks 6.These guides, in this instance, travel in bearings T formed at the upperends of the frame pieces, the blocks 6 cooperating with the side piecesto limit the movement of the support for the material in its twodirections of movement.

The cutter 4 is preferably secured to a shaft 8 which connects to twoframe pieces l and has a rotary as well as an axial movement in saidframe pieces. This shaft may be provided with a screw 9 and on thisscrew a nut or internally threaded sleeve lil may operate. This sleeveis held against axial movement in fin v suitable manner as in the mannerhereinafter described.

It is apparent that if the shaft is permitted to turn freely in the nut`the shaft will move axially whereas, if the nut is locked to the shaft,the nut will turn and at he same time the shaft will be held againstaxial movement. In order to effect this con nection and disconnection ofthe nut with the shaft. a breakable connection is provided which in thisinstance consists of i.

sliding key 11 movable in a longitudinal extending groove or way 12 inthe shaft and adapted at one end to enter into a notch or opening 13 inthe nut. For the purpose of operating this key, the latter has a collar14 rigidly secured thereto and surrounding the shaft 8. rIhis collar isacted upon by a helical spring 15 which surrounds the shaft and abutsthe sliding collar 14 at one end and at its other end a collar 1G isrigidly and adjustably secured to the shaft 8 by a set screw 1T. Thespring normallv holds the key ll in connection with 'the nut 1d. inorder to effect the disconnection of the nut with the shaft so as topermit the shaft to turn in the nut, the collar 14 may be provided withan annular groove 20. ln this groove a yoke 21 operates, said yoke beging secured to the upper end of an arm 22 which at its lower end ispivoted at to the supporting base 2. An arm 24 extends late ally fromthe lower end of the arm 22 and upon the depression of the arm 24th@collar 14 will be moved to move the key 11 out of connection with thenut. Automatic means may also be provided for breaking the connectionbetween the nut and the screw shaft, one embodiment of such means beinghereinafter fully described. l

Any suitable means may be employed for moving the support 3 for thematerial to be sliced transversely of the axis of turning of the cuttershaft. In this'embodiment, this support movement is produced through aconnection with the cutter shaft and to this end the nut 10 is providedon its periphery with teeth Q5 which cooperate with upwardly presentedteeth on a rack QG, this rackbeing suspended by brackets 2T from theunder side of the support 3. it is apparent that rotation of the shaft Syhv any suitable means such as a crank handle 2S, when the nut 10 isinterlocked with the shaft, will'produce a movement of the supporttransversely of the shaft through the rack 26 and the gear teeth 25. Therack bar 26 is utilized for preventing` the axial movement of the nut 10and to this end, the nut is provided with annular flanges 10a onopposite sides of the teeth 25, these flanges cooperating with oppositesides of the rack bar to prevent the axial movement. Beneath the rackbar at a point directly below the nut, one of the frame members may beprovided with a proj ecting portion 29 which cooperates with the underside of the rack bar to maintain cooperation between the rack bar andthe teeth 25.

lith the end in view of effecting the automatic shifting of the cuttershaft in the direction of the axis of said shaft, the suptance betweenthe collar 14 and the nut 10 when the collar is in the position to holdthe nut so that the shaft is interlocked therewith, whereas, thethickness of the latchor detent in rear of said tapered portion isgreater than the distance between the collar 14 and the nut 10. rIhepivoted latch or detent 30 is so arranged on the support that when thelatter has reached one end of its movement, the tapered end will passbetween the collar 14 and the nut 1() and move said collar in thedirection of the axis of the shaft S so as to break the connectionbetween the shaft and the nut, permitting the shaft 8 to turn in the nutand in this way move the cutter axially toward the support 3 for thematerial. ln this embodiment, the shaft 8 makes only one rotation beforethe interlocking connection between said shaft 8 and the nut 10 isrestablished. This restablishment is effected in this instance byprojection 33 on the face of the collar 14 opposed to the nut. TheVprojection engages the under side of the latch 30 and moves said latchupwardly in the manner shown in Fig. l2, out of the position between thecollar 14 and the nut 10, after 4which the spring 15 will move thecollar 14 so that the key 11 will reestablish connection between the nut10 and the shaft 8. The dog or latch being wider than the distancebetween the collar 14 and the nut 10, will rest upon these parts sothat, when the shaft is rotated in a reverse direction, the dog will becarried away from such parts to Vthe other extreme movement of thesupport 3 to again separate theY parts upon the next approach thereto.1n order to limit the axial movement of the shaft in two directions, twostops 34 and35 are provided, one of these stops cooperating with thecollar 16 andthe other stop cooperating with a collar 36 on the shaft,both stops being in the form of screws and being adjustable. v

The material may be held on the support 3 in any suitable manner. It ispreferred however, to provide the upper surface of the support with aplurality of projections 37 and'to mount on the support, a plunger 38having a clamping head 39 at its lower end and a handle 40 at its upperend by which the clamping head may be elevated against the action of thespring 41 which surrounds the plunger 38. The plunger 33 may be guidedin a bracket 42 which is supported from the support 3. The operation ofthe invention will be understood from the foregoing, but it may besummarized as follows:

The meat or other material is secured upon the support 3 under theclamping head 39 to project beyond the support 3 in the path of thecutter 4. The crank handle is then turned which moves the support 3transversely of the cutter shaft 8 and causes the rotary blade 4 toslice the material on the support. Upon the return movement ofv -in theopposite direction another slice will be cut from the material. Thisoperation is continued until the knife or critter 4 approaches theproximate edge of the support 3. lWhen this position is reached, thelever arm 24 is depressed, shifting the collar 14 to break theconnection between the shaft and the nut l0. The shaft is then turned ina direction to cause the cutter or knife t'o be moved away from thesupport 3 and, when the desired position of the knife is reached, thelever 24 is released permitting the connection between the shaft S andthe nut to be restablished.

lrom the foregoing it will be seen that there has been provided a rotarycutter movable axially and combined with a support for the material tobe sliced movable transversely of the axis of rotation of the cutter. Adriving connection is provided between the shaft of the cutter andthesupport, this driving connection preferably being breakable so that theshaft may be moved axially independently of the support. Means is alsoprovided whereby the cutter shaft may be moved automatically when thesupport reaches a certain position. This automatic means is preferablyin the form of a dog carried by the support and coperating with thebreakable connection.
